<p>These modules were added very early in CMake's development to support
driving tests with a &quot;DART&quot; tool, but DART has not been distributed or
maintained for many years.  Projects would <code class="docutils literal notranslate"><span class="pre">include(Dart)</span></code> to use it,
and the <code class="docutils literal notranslate"><span class="pre">Dart</span></code> module would run <code class="docutils literal notranslate"><span class="pre">find_package(Dart)</span></code> internally.
Since <span class="target" id="index-0-manual:ctest(1)"></span><a class="reference internal" href="../manual/ctest.1.html#manual:ctest(1)" title="ctest(1)"><code class="xref cmake cmake-manual docutils literal notranslate"><span class="pre">ctest(1)</span></code></a> was created, the <code class="docutils literal notranslate"><span class="pre">Dart</span></code> module has just been
a compatibility shim that finds <code class="docutils literal notranslate"><span class="pre">Dart</span></code> to support some legacy
functionality and then forwards to the <span class="target" id="index-0-module:CTest"></span><a class="reference internal" href="../module/CTest.html#module:CTest" title="CTest"><code class="xref cmake cmake-module docutils literal notranslate"><span class="pre">CTest</span></code></a> module.</p>
<p>CMake 3.27 and above prefer to not provide the <span class="target" id="index-1-module:Dart"></span><a class="reference internal" href="../module/Dart.html#module:Dart" title="Dart"><code class="xref cmake cmake-module docutils literal notranslate"><span class="pre">Dart</span></code></a> or
<span class="target" id="index-1-module:FindDart"></span><a class="reference internal" href="../module/FindDart.html#module:FindDart" title="FindDart"><code class="xref cmake cmake-module docutils literal notranslate"><span class="pre">FindDart</span></code></a> modules.  This policy provides compatibility for
projects that have not been ported away from them.  Projects using the
<code class="docutils literal notranslate"><span class="pre">Dart</span></code> module should be updated to use the <span class="target" id="index-1-module:CTest"></span><a class="reference internal" href="../module/CTest.html#module:CTest" title="CTest"><code class="xref cmake cmake-module docutils literal notranslate"><span class="pre">CTest</span></code></a> module directly.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior of this policy is for <code class="docutils literal notranslate"><span class="pre">include(Dart)</span></code> and
<code class="docutils literal notranslate"><span class="pre">find_package(Dart)</span></code> to load the deprecated modules.  The <code class="docutils literal notranslate"><span class="pre">NEW</span></code>
behavior is for uses of the modules to fail as if they do not exist.</p>
<p>This policy was introduced in CMake version 3.27.  CMake version
3.27.4 warns when the policy is not set and uses <code class="docutils literal notranslate"><span class="pre">OLD</span></code> behavior.
Use the <span class="target" id="index-0-command:cmake_policy"></span><a class="reference internal" href="../command/cmake_policy.html#command:cmake_policy" title="cmake_policy"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">cmake_policy()</span></code></a> command to set it to <code class="docutils literal notranslate"><span class="pre">OLD</span></code> or <code class="docutils literal notranslate"><span class="pre">NEW</span></code>
explicitly.</p>
